What people are doing:
------
AD integration
- clients and or server +++
AFP performance fixing
RAID issues
standalone Mac labs
Cluster...
Incoming Macs, how to deal with in a Windows shop++
- final, locked down management solution?
Small schools, large schools, scalable solutions?
Gene shows WordPress
- free and extensible
What helpdesks are people using (and what inventory tracking systems?)
- Request Tracker
- Webhelpdesk
- Gene Showing off ticketing, inventory tracking tied to users
- repair history
- Discovery Tool plugs into ARD, LANRev, Casper
- easy importing from FM Pro
- licensing per Admin
- http://www.webhelpdesk.com/
- Heat
Splunk
- Web based, logging centralization and notifaction
- Very easy tool gives you one place too look at logs, and never have to worry about custom logging configuration and scripting (os x servers and clients can log to a central server, and send notifications)
- Logs are the first place you should check when you have failures!
- Splunk saved searches across all OS X system logs, for terms like "error", "failure", and will email you ...
- Service plugins easily available
Support standards?
- Cherry Creek 6 years old wont be supported, 10.5 and 10.6 only.
- site based upgrades.
- Manitou
- 5 years servers and clients, AppleCare for everything, send hardware repairs to Apple.
Xavier from MSSD showing off his SMB setup
- Windows PDC, BDC, windows machines logging into OS X Server no problem.

<--!! Mike's Notes
Kens notes
Glen Worthing's Notes/questions
"Best practices" for using Apple equipment school.
Questions like the minimum services that an Xserv should run (for example, I'm not running DNS, should I for better performance)?
If multiple Apple Xservs are available, would you split out the services between the servers and if so, which one's would you split out?
If multiple Apple Xservs are available, would you have one be a standalone or replica?
Local logins, or network logins (home directories) for computer labs and for teachers?
Perform Apple updates throughout the year or stick with image that is deployed at the beginning of the year?
What is the best instruction for VPN connection setup?? Would I set up through our Sonicwall or Apple Server or both?

AFP Users not getting disconnected:

Subject: Re: [Rockies-Edu] AFP not releasing users
To: email@hidden
Here is a chunk of text that is a cross-post from other lists. Please
read carefully and let me know if this change does not help with your
idle AFP connections. Hope this helps.
---
Open Terminal, and su to root:
Last login: Thu Mar 29 17:04:36 on ttyp1
Welcome to Darwin!
server:~ username$
server:~ username$ su root
Password:
Then, although this is something you've probably already done, confirm
that the maximum number of threads for AFP is set to a reasonable value:
server:/Users/username root# serveradmin settings afp:maxThreads
What you will see, if it's still set to the default, is 40.
afp:maxThreads = 40
40 is default, and if you have many users, you may wish to set a
higher value. It's been established by others through experimentation
that 300 to 400 is as high as you should go, assuming your server has
plenty of RAM (2GB or more):
server:/Users/username root# serveradmin settings afp:maxThreads=300
afp:maxThreads = 300
Now, for the kicker. This parameter, "reconnectTTLInMin", is not the
same parameter that is set when you adjust the "disconnect idle users
after _x_ minutes" value in Server Admin, but is related to that
function:
server:/Users/username root# serveradmin settings afp:reconnectTTLInMin
afp:reconnectTTLInMin = 1440
The default for this parameter is 1440 minutes, which is a full day.
But it SEEMS that if it's set to such a high value, something gets
"stuck" somewhere else, and these connections are never updated if the
machine that fell asleep wakes back up or is shut down or rebooted...
there will probably be some side effects from making this change; you
may try other values, but the customer who helped me nail this down
chose 10 minutes:
server:/Users/username root# serveradmin settings afp:reconnectTTLInMin=20
afp:reconnectTTLInMin = 20
I THINK that this parameter may define a time after which a sleeping
machine is able to reconnect the to the server, but there is a
separate session-caching algorithm that affects this, too. Further
experimentation with this parameter, and with machines that have been
asleep for longer than the value set, is indicated, but I wanted to
get the information to my afflicted customers as quickly as possible.
The serveradmin Terminal command allows you to view, or change, any
parameter in the AFP plist config file, /Library/Preferences/
com.apple.AppleFileServer.plist. In later versions of Mac OS X Server
10.4, this file is no longer straight text; if you wish to examine a
copy, so you can see what the parameters in this file include, you may
either view it with a plist editor such as included with the Developer
Tools, or convert A COPY of it to text, as follows:
server:/Users/username root# cp /Library/Preferences/
com.apple.AppleFileServer.plist /Library/Preferences/
com.apple.AppleFileServer.plist.copy
server:/Users/username root# plutil -convert xml1 /Library/
Preferences/com.apple.AppleFileServer.plist.copy
Each of the two commands above is a SINGLE LINE which has wrapped in
this email. The first one contains just two spaces in the text you
must enter, and the second has three, so be careful entering them.
This command will convert the "compiled" plist copy to a straight text
xml file:
server:/Users/username root# plutil -convert xml1 /Library/
Preferences/com.apple.AppleFileServer.plist.copy
And this one will let you have a look at it:
server:/Users/username root# more /Library/Preferences/
com.apple.AppleFileServer.plist.copy
To summarize, these settings are the most important ones to which you
may make adjustments, and the second one is the magic one. The actual
numeric values you'd like to apply could fall over a range that has
not yet been defined; you are welcome to experiment.
serveradmin settings afp:maxThreads=300
serveradmin settings afp:reconnectTTLInMin=10
But REMEMBER these two things:
AppleFileServer must be stopped, and restarted, for these values to go
into effect.
Only convert a COPY of the file to text for viewing, NEVER the original.
